CASTER.

To all whom it may concern:

Be it known that I, WILLIAM GOLDBACH, a subject of the Emperor ofGermany, residing at Meriden, county of New Haven, State of Connecticut,have invented an Improvement in Casters, of which the following is aspecification.

This invention has for its object to provide a simple, strong andinexpensive caster adapted for general use in furniture as in eithermetal or wooden bedsteads and which shall be so constructed as to beself-retaining in place without danger of dropping out in the ordinaryconditions of use.

With these and other objects in view I have devised the novel casterwhich I will now describe, referring to the accompanying drawing forminga part of this specification and using reference characters to indicatethe several parts.

Figure 1 is a section of a furniture leg showing my novel caster inplace therein, portions of the caster being broken away to show the modeof construction; Fig. 2 an elevation partly broken away of the casterdetached, the point of view being from the right as seen in Fig. 1; Fig.3 a section on the line 3-3 in Fig. 1 looking in the direction of thearrows; and Fig. 4 is a perspective of the spring frame detached.

10 denotes the yoke, 11 the wheel and 12 the pintle to which the yoke isrigidly secured. The special construction of the pintle and yoke iswholly immaterial so far as the present invention is concerned. I haveshown the pintle as provided near its lower end with a hub 13 having aflange 20 which forms a bearing for the disk, presently to be described,and below the hub with a stud 31 which passes through the yoke andthrough a strengthening washer 14: and is headed down upon the washer asat 15, thus rigidly securing the pintle and yoke together. The wheel maybe of any suitable material as wood, glass or metal or metal coveredwith rubber or felt. The novelty of my invention lies in the specialconstruction of the disk, inclicated by 16, and the frame, indicated by17 and the manner in which they are connected together so as to give themaximum of spring power to the frame. In practice these parts are madeby multiple acting punches and a complete part is turned out at eachblow of the press. In use the disk lies closely against the end of afurniture leg which is indicated by 18. The disk is pro- Specificationof Letters Patent.

vided with a central hole 19 through which the hub passes, the hub beingprovided with flange 20 upon which the disk rests and supporting theentire weight to be carried.

21 denotes lugs in pairs which are struck out from the metal of the diskand extend gptlvard at right angles to the plane of the The frame isformed from sheet metal, which may be provided in strips, and comprisesa top 22 having a central hole 23 through which the pintle passes,spring sides 24 which are preferably slightly bowed outward, as shown inpossible spring action and inwardly turned arms 25 at the lower ends ofthe sides which are shown as provided in their ends with recesses 26 togive clearance to the hub and are provided back of the recesses withslots 27 which are of sufficient length to receive the pairs of lugs onthe disk freely and of a width enough greater than the width of the lugsto permit ample spring movement of the sides when the frame is driveninto the 1 socket, indicated by 28, in the furniture leg. The metalsurrounding central hole 23 in the top of the frame is preferably turnedinward forming a flange 29 which bears on the pintle, the frame and diskbeing secured in place on the pintle by a heading 30 which howeverleaves the pintle free to rotate independently of the disk and frame.

The operation will be obvious from the drawing. The caster is assembledby placing the yoke and a washer over stud 31 and then heading the endof the stud down rigidly upon the washer, thus locking the yoke to thepintle. The disk is then placed over the pintle, then the frame isplaced over the intle with the pairs of lugs passing through slots 27 inthe inwardly turned arms and the disk and frame are secured in place byheading down the end of the pintle loosely leaving the pintle free torotate independently of the frame and disk. The caster is attached inplace by simply driving the spring frame into the socket in a furnitureleg until the disk bears against the end of the leg, the sides of theframe yielding as it is driven into the socket. As these side pieces arepreferably outwardly bowed and as without regard to their specialconfiguration they have a strong outward spring action, the pressure ofthe frame against the wall of the socket in the furniture leg willretain the caster securely in place.
